MULTI THERMOCOUPLE FOR GAS TURBINE EXHAUST GAS

摘要

A multi thermocouple for gas turbine exhaust gas is provided to prevent damage and bending due to vibration or bending by measuring the temperature without direct contact with inner part of the gas turbine. A fixing unit(10) is installed at an exhaust gas outlet of a gas turbine. An external protection part(30) is inserted into the fixing unit and is combined to the fixing unit. An internal protection part(50) is inserted into the external protection part and is combined to the external protection part. A thermal sensor(70) is installed in an internal protection part and senses the heat of the exhaust gas. A first coupling unit(20) couples the fixing unit with the external protection part. A second coupling unit(40) couples the external protection part with the internal protection part.
